============================================================================= - generate single subject analysis review scripts

        o  figure out basic details (sid, trs, xmat, censor stats files, etc.)
        o  generate an @ss_review_basic script to output simple details about
           this subject and results
        o  generate a @ss_review_driver script to actually inspect the results
           (running some commands by the user's control)
        o  generate @ss_review_driver_commands
           (same as @ss_review_driver, but a pure command file)

   Consider following this with, after many/all
   subjects are analyzed.  For example:

      cd subject_results -tablefile review_table.xls \
          -infiles group.*/subj.*/*.results/out.ss_review.*



      1. Run this program without any options, assuming everything is there.


         Additional run the basic review script and then the drive script.


      2. Esoteric.  Set all the output file names (for now via control vars).

                        -cvar scr_basic ~/tmp/s.basic \
                        -cvar scr_drive ~/tmp/ \
                        -cvar cmds_drive ~/tmp/s.cmds \
                        -cvar xstim ~/tmp/x.stim.1D

       2b. Similar to 2, but put all scripts and intermediate files under
           a new ~/tmp/gen_dir.  So as an example for testing:

                mkdir ~/tmp/gen_dir
       -cvar out_prefix ~/tmp/gen_dir/

           Note that if out_prefix is a directory, it will need a trailing
           '/', since it is a file name prefix.

       2c. Simplified.  Use -prefix instead of -cvar out_prefix.

       -prefix test.

       3a. Show the list of computed user variables.


       3b. Also, write uvars to a JSON file.

       -show_computed_uvars \
                                         -write_uvars_json user_vars.json

       3c. Also, initialize uvars from a JSON file (as done by

       -exit0                \
                    -init_uvars_json out.ap_uvars.json         \
                    -ss_review_dset out.ss_review.$subj.txt    \

Here are some potential artifacts to ponder (just so they are saved
somewhere), as noted by many of us, including D Glen and J Gonzalez.
We can try to add to this list, and maybe even do something to take
them off <gasp!>.

    1. Striping - across slices - EPI, anatomical
    2. Artifacts - checkerboard, ringing - EPI, anatomical
    3. Spiking (regional or global)
        - global would be caught in the outlier fractions
    4. Shifts in baseline (regional or global)
        - maybe @ANATICOR can help to deal with it, but how to notice?
    5. "PURE" on or off / acquisition protocol changes
    6. Poor contrast between CSF and WM/GM in EPI
    7. Low resolution anatomical data
    8. Noisy anatomical data
    9. Left-right flipping between anatomical and EPI
        - run between flipped versions
          (as was done by _____ on the fcon_1000 data)
   10. Poor alignment between anatomical and EPI
        - currently users can view as part of @ss_review_driver
        - can use some large limit test on value from out.mask_overlap.txt
   11. Excessive motion
        - currently report average motion and censor details
   12. "Reshimming-like" shears between EPI volumes
   13. Non-uniformity because of surface coils
   14. Incorrect DICOM data
   15. Inconsistent data types within a study
   16. TR not properly set
   17. Missing data
   18. Inconsistent number of TRs within multiple EPI datasets
   19. Missing pre-steady state in EPI data
